///*
//DEPRECATED APIS
//===============
//Version 0.9.0 deprecated the per-sample reading and seeking APIs and replaced them with versions that work on the resolution
//of a PCM frame instead. For example, given a stereo WAV file, previously you would pass 2 to drwav_read_f32() to read one
//PCM frame, whereas now you would pass in 1 to drwav_read_pcm_frames_f32(). The old APIs would return the number of samples
//read, whereas now it will return the number of PCM frames. Below is a list of APIs that have been deprecated and their
//replacements.
//
//    drwav_read()                     -> drwav_read_pcm_frames()
//    drwav_read_s16()                 -> drwav_read_pcm_frames_s16()
//    drwav_read_f32()                 -> drwav_read_pcm_frames_f32()
//    drwav_read_s32()                 -> drwav_read_pcm_frames_s32()
//    drwav_seek_to_sample()           -> drwav_seek_to_pcm_frame()
//    drwav_write()                    -> drwav_write_pcm_frames()
//    drwav_open_and_read_s16()        -> drwav_open_and_read_pcm_frames_s16()
//    drwav_open_and_read_f32()        -> drwav_open_and_read_pcm_frames_f32()
//    drwav_open_and_read_s32()        -> drwav_open_and_read_pcm_frames_s32()
//    drwav_open_file_and_read_s16()   -> drwav_open_file_and_read_pcm_frames_s16()
//    drwav_open_file_and_read_f32()   -> drwav_open_file_and_read_pcm_frames_f32()
//    drwav_open_file_and_read_s32()   -> drwav_open_file_and_read_pcm_frames_s32()
//    drwav_open_memory_and_read_s16() -> drwav_open_memory_and_read_pcm_frames_s16()
//    drwav_open_memory_and_read_f32() -> drwav_open_memory_and_read_pcm_frames_f32()
//    drwav_open_memory_and_read_s32() -> drwav_open_memory_and_read_pcm_frames_s32()
//    drwav::totalSampleCount          -> drwav::totalPCMFrameCount
//
//Rationale:
//    1) Most programs will want to read in multiples of the channel count which demands a per-frame reading API. Per-sample
//       reading just adds complexity and maintenance costs for no practical benefit.
//    2) This is consistent with my other decoders - dr_flac and dr_mp3.
//
//These APIs will be removed completely in version 0.10.0. You can continue to use drwav_read_raw() if you need per-sample
//reading.
//*/
//
//// USAGE
////
//// This is a single-file library. To use it, do something like the following in one .c file.
////     #define DR_WAV_IMPLEMENTATION
////     #include "dr_wav.h"
////
//// You can then #include this file in other parts of the program as you would with any other header file. Do something
//// like the following to read audio data:
////
////     drwav wav;
////     if (!drwav_init_file(&wav, "my_song.wav")) {
////         // Error opening WAV file.
////     }
////
////     drwav_int32* pDecodedInterleavedSamples = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32));
////     size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedSamples);
////
////     ...
////
////     drwav_uninit(&wav);
////
//// You can also use drwav_open() to allocate and initialize the loader for you:
////
////     drwav* pWav = drwav_open_file("my_song.wav");
////     if (pWav == NULL) {
////         // Error opening WAV file.
////     }
////
////     ...
////
////     drwav_close(pWav);
////
//// If you just want to quickly open and read the audio data in a single operation you can do something like this:
////
////     unsigned int channels;
////     unsigned int sampleRate;
////     drwav_uint64 totalPCMFrameCount;
////     float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount);
////     if (pSampleData == NULL) {
////         // Error opening and reading WAV file.
////     }
////
////     ...
////
////     drwav_free(pSampleData);
////
//// The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in
//// this case), but you can still output the audio data in its internal format (see notes below for supported formats):
////
////     size_t samplesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedSamples);
////
//// You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for
//// a particular data format:
////
////     size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer);
////
////
//// dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at
//// drwav_open_write(), drwav_open_file_write(), etc. Use drwav_write_pcm_frames() to write samples, or drwav_write_raw()
//// to write raw data in the "data" chunk.
////
////     drwav_data_format format;
////     format.container = drwav_container_riff;     // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64.
////     format.format = DR_WAVE_FORMAT_PCM;          // <-- Any of the DR_WAVE_FORMAT_* codes.
////     format.channels = 2;
////     format.sampleRate = 44100;
////     format.bitsPerSample = 16;
////     drwav* pWav = drwav_open_file_write("data/recording.wav", &format);
////
////     ...
////
////     drwav_uint64 samplesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples);
////
////
//// dr_wav has seamless support the Sony Wave64 format. The decoder will automatically detect it and it should Just Work
//// without any manual intervention.
////
////
//// OPTIONS
//// #define these options before including this file.
////
//// #define DR_WAV_NO_CONVERSION_API
////   Disables conversion APIs such as drwav_read_pcm_frames_f32() and drwav_s16_to_f32().
////
//// #define DR_WAV_NO_STDIO
////   Disables drwav_open_file(), drwav_open_file_write(), etc.
////
////
////
//// QUICK NOTES
//// - Samples are always interleaved.
//// - The default read function does not do any data conversion. Use drwav_read_pcm_frames_f32(), drwav_read_pcm_frames_s32()
////   and drwav_read_pcm_frames_s16() to read and convert audio data to 32-bit floating point, signed 32-bit integer and
////   signed 16-bit integer samples respectively. Tested and supported internal formats include the following:
////   - Unsigned 8-bit PCM
////   - Signed 12-bit PCM
////   - Signed 16-bit PCM
////   - Signed 24-bit PCM
////   - Signed 32-bit PCM
////   - IEEE 32-bit floating point
////   - IEEE 64-bit floating point
////   - A-law and u-law
////   - Microsoft ADPCM
////   - IMA ADPCM (DVI, format code 0x11)
//// - dr_wav will try to read the WAV file as best it can, even if it's not strictly conformant to the WAV format.

//// REVISION HISTORY
////
//// v0.9.0 - 2018-12-16

////       drwav_open_file_and_read_s32()   -> drwav_open_file_and_read_pcm_frames_s32()
////       drwav_open_memory_and_read_s16() -> drwav_open_memory_and_read_pcm_frames_s16()
////       drwav_open_memory_and_read_f32() -> drwav_open_memory_and_read_pcm_frames_f32()
////       drwav_open_memory_and_read_s32() -> drwav_open_memory_and_read_pcm_frames_s32()
////       drwav::totalSampleCount          -> drwav::totalPCMFrameCount
////   - API CHANGE: Rename drwav_open_and_read_file_*() to drwav_open_file_and_read_*().

////     - This is enabled through the drwav_init_ex(), etc. family of APIs.
////   - Handle invalid FMT chunks more robustly.
////
//// v0.8.5 - 2018-09-11
////   - Const correctness.
////   - Fix a potential stack overflow.
////

////   - Fix a crash when reading 16-bit floating point WAV files. In this case dr_wav will output silence for
////     all format conversion reading APIs (*_s16, *_s32, *_f32 APIs).
////   - Fix some divide-by-zero errors.
////
//// v0.7b - 2018-01-22
////   - Fix errors with seeking of compressed formats.
////   - Fix compilation error when DR_WAV_NO_CONVERSION_API
